Abstract

Arctigenin and demethyltraxillagenin, dibenzylbutyrolactone lignans, are phenylpropanoid plant metabolites with antioxidative and anti-inflammatory activities. The effects of arctigenin and demethyltraxillagenin on the nuclear factor-kB (NF-kB)-mediated inducible nitric oxide synthase (iNOS) gene expression were studied in Raw264.7 cells.(omitted)
